RESUMO

Research has documented neurophysiological indicators of anticipation (Stimulus Preceding Negativity [SPN]) and perception (Late Positive Potential [LPP]) of threat, yet little is known as to how self-focused attention manipulations influence emotion processing within the context of cued picture viewing. With self-referent attention moderating attention to external stimuli, it is necessary to document how self-focused attention impacts attention and the ability to emotionally process external threat. The goal of the present study was to evaluate the impact of self-focused attention on the anticipation and perceptual processing of unpleasant pictures within a cued-picture viewing paradigm among 33 participants. Overall, the results suggest that the self-focused attention manipulations disrupted anticipation but not processing of pictures, as indexed by the SPN and LPP respectively. Self-focused attention appears to disrupt the preparatory attention for upcoming unpleasant stimuli, potentially through loading cognitive resources or activation of associative defensive responding. Collectively, these findings demonstrate the impact of self-focused attention within the context of emotional picture processing and suggest further areas of investigation.

RESUMO

Models of social anxiety propose that negative self-imagery is a maintenance factor of psychopathology, yet the mechanisms of this relationship are unclear. One proposed mechanism is attention towards self-images. However, self-image creation does not occur in isolation and is likely influenced by other mechanisms, such as anticipatory processing (AP). The current study aimed to investigate how trait social anxiety and AP influence motivated attention during self-imagery (i.e., late-positive potential; LPP). Participants (N = 40) with a mean age of 18.95 (SD = 1.22) completed AP manipulations and a self-imagery task. Results revealed that participants with high levels of social anxiety who engaged in AP demonstrated blunted LPP activity in the late time window (6000-10,000 ms) relative to those who engaged in Distraction. These results suggest that motivated attention towards self-imagery may be impacted by anticipatory processing, but less influenced by the valence of self-imagery. Given previous research has been limited in methodology, this study expands upon current research by documenting the neural mechanisms of self-imagery manipulations within social anxiety.

RESUMO

The Social Anxiety Questionnaire (SAQ) is a 10-item measure of social anxiety developed to comprehensively and concisely target the mechanisms described in Clark and Wells' model of social anxiety and address the breadth of social anxiety symptoms which may not all be encompassed in existing questionnaires. The aim of the current studies is to independently investigate the factor structure of the SAQ (i.e., Study 1 and 2) and determine its predictive validity and utility (i.e., Study 3 and 4). Data were collected across 4 studies to evaluate the factor structure and utility. Overall, the results suggest that a total summed score of the SAQ appeared to capture unique aspects of social anxiety that may not be captured using a single measure and appears to provide utility in experimental manipulations of theoretical maintenance factors. The current study was limited by a convenience sample and future research should continue to document the psychometric properties and clinical utility of this novel measure of social anxiety. The SAQ may show promise in both correlational and experimental research but future research should consider further evaluation of its utility.

RESUMO

Research attempting to identify pathways from childhood maltreatment to adulthood posttraumatic stress symptoms (PTSS) implicates cognitive vulnerabilities that may increase risk for mental health concerns. The present study examined two cognitive vulnerabilities and their relation to PTSS amongst individuals with and without childhood maltreatment histories: attentional control and repetitive negative thinking (RNT). This research surveyed college students (N = 376) on constructs of interest. Results revealed that attentional control and RNT demonstrated significant indirect effects on PTSS (95% CI =.0003, .0336 and 95% CI =.0643, .1857, respectively). Findings suggest that childhood maltreatment severity was related to decreased attentional control and increased RNT, which were then both related to increased PTSS. Interventions for increasing attentional control and decreasing RNT should be implemented and evaluated for young adults with early adversity currently experiencing PTSS.

RESUMO

OBJECTIVE: Social anxiety and depression are commonly comorbid and cause significant impairment in college students. Past research suggests that both poor attentional control and increased rumination are related to these disorders and independently mediate their relationship. Theory suggests that social anxiety loads working memory, thus decreasing attentional control, which influences rumination and depression. The current study aimed to investigate the potential combined influence of attention control and rumination on social anxiety and depression. Participants: Participants (80) were recruited from a large Midwestern university in September 2017. Methods: Participants completed questionnaires regarding social anxiety, attentional control, rumination, and depression and data were analyzed using bias-corrected bootstrapping analyses. Results: Results demonstrate a significant indirect relationship between social anxiety and depression through attentional control and rumination. Conclusions: Results indicated that college students with social anxiety may be at risk for depression due to decreased attentional control and increased rumination. Clinical implications are discussed.

RESUMO

OBJECTIVE: Data indicate that adverse childhood experiences (ACEs) are a risk factor for cognitive and attentional vulnerabilities. A vulnerability linked to these impairments is repetitive negative thinking (RNT), and data suggest that RNT and anxiety symptoms may be moderated by attentional control. The current study investigated the effect of these risk factors on symptoms of anxiety. Participants: College students (N = 376) were recruited from a university. Methods: Participants were administered questionnaires online to assess retrospective ACEs, current RNT, attentional control, and anxiety symptoms. Results: There was an indirect effect of ACEs on anxiety symptoms through RNT. High attentional control moderated the indirect effects, such that high compared to low attentional control was associated with an increased effect of RNT on anxiety symptoms. Conclusions: Increased ACEs may be a risk factor for RNT among college students. Combined with high attentional control, these may be risk factors for anxiety symptoms.

RESUMO

Investigations of fear conditioning have recently begun to evaluate contextual factors that affect attention-related processes. However, much of the extant literature does not evaluate how contextual fear learning influences neural indicators of attentional processes during goal-directed activity. The current study evaluated how early attention for task-relevant stimuli and conflict monitoring were affected when presented within task-irrelevant safety and threat contexts after fear learning. Participants (N = 72) completed a Flanker task with modified context before and after context-dependent fear learning. Flanker stimuli were presented in the same threat and safety contexts utilized in the fear learning task while EEG was collected. Results indicated increased early attention (N1) to flankers appearing in threat contexts and later increased neural indicators (P2) of attention to flankers appearing in safety contexts. Results of this study indicate that contextual fear learning modulates early attentional processes for task-relevant stimuli that appear in the context of safety and threat. Theoretical and clinical implications are discussed.

RESUMO

Attentional control has grown in importance within theoretical and predictive models of psychopathology over past decades. The Attentional Style Questionnaire (ASQ) is a novel measure of internal and external attentional control. However, no study has independently validated this questionnaire. Two studies assessed the factor structure for the ASQ within an English-speaking population (Study 1), evaluated the construct and content validity, and assessed incremental predictability (Study 2). Results of Study 1 observed two factors that could be characterised as distractibility/cognitive avoidance and focusing, whereas the original study had observed factors defined as internal and external. Results of Study 2 confirmed the factor structure of Study 1, in addition to providing evidence for the ASQ's predictability for anxiety, depression and worry behaviours above established measures of attentional control. Overall, these results indicated that the ASQ measures factors of attentional control which provides incremental utility for predicting psychopathology. Implications on psychopathology and discrepancies to previous findings are discussed.

RESUMO

Social anxiety disorder (SAD) and major depressive disorder (MDD) are comorbid conditions, and SAD confers risk for MDD. Biased attention and interpersonal rejection are important for the development of SAD and MDD, but little research has examined how these processes may lead to MDD. We hypothesized that interpersonal rejection would result in SAD symptoms being associated with more "depression-like" attention biases. Participants (n = 164) completed a measure of SAD symptoms and an eye tracking task before and after a task in which they were randomized to be socially included or rejected. SAD symptoms, inclusion or rejection condition, and the interaction term were entered into separate hierarchical linear regressions predicting change in attention for five emotional faces. Rejection condition significantly moderated the effects of SAD on change in attention to sad, happy, and neutral faces. SAD predicted increased attention to sad faces and decreased attention to happy faces in the rejection condition, but not in the inclusion condition. SAD predicted increased attention to neutral faces in the inclusion condition, but not in the rejection condition. There were no significant effects for angry or disgust. Results suggest that SAD symptoms are associated with more depression-like attention biases in the context of interpersonal rejection.

RESUMO

The emotional cascade model proposes that the emotional instability and engagement in maladaptive behaviors within borderline personality disorder (BPD) may be linked to rumination. Previous research has established that BPD is highly related to neuroticism, childhood emotional vulnerability, and parental invalidation. Therefore, the purpose of the current study was to assess whether the constructs of the emotional cascade model relate to other constructs within the BPD nomological network. More specifically, neuroticism, childhood emotional vulnerability, and parental invalidation should relate to the ruminative process and engagement in maladaptive behaviors as described by the emotional cascade model. The current study investigated the relation between these factors using a cross-lagged panel design with data collected online at 3 time points in a student sample and an Amazon Mechanical Turk sample. Neuroticism predicted rumination 1 month later across both samples and for 3 measures of rumination. Childhood emotional vulnerability and parental invalidation predicted rumination 2 months later for 2 measures of rumination in the student sample only. Future studies should continue to investigate the potential role of personality traits and BPD vulnerability factors within the emotional cascade model.

RESUMO

High social anxiety is associated with increased attentional bias, and difficulties disengaging from relevant threat information, though social anxiety may also be associated with avoidance of threat. Few mechanisms of this relationship have been empirically evaluated, whereas theories and treatment manuals implicate avoidance and/or safety behaviors as significant agents of negative reinforcement for anxiety symptoms and search for threat. The current study sought to investigate one safety behavior, excessive reassurance seeking, as a mediator of the relationship between social anxiety and attention bias to disgust facial stimuli. Support was found for our hypotheses, such that social anxiety symptoms had an indirect effect on attention bias to disgust faces through increased reassurance seeking. These results suggest that reassurance seeking may result in disengagement of attention to threat stimuli. Specifically, social anxiety may result in a decreased threshold for negative social cues and therefore seek out reassurance feedback and avoid threatening stimuli. Future studies should test these directly and utilize a prospective design. The current study suggests that reassurance seeking may be involved in the attention bias process, providing additional data for current cognitive theories of social anxiety and additional support for reinforcement patterns of anxiety symptoms.

RESUMO

OBJECTIVE: To identify a developmentally relevant factor structure of the Mishel Uncertainty in Illness Scale-Community form (MUIS-C) among adolescents and young adults with chronic medical conditions. METHODS: Data on college students with a self-reported chronic medical condition (N = 238) were collected between November 2013 and May 2015. Participants completed the MUIS-C as part of a larger questionnaire battery. An exploratory factor analysis and a confirmatory factor analysis were conducted. RESULTS: The exploratory factor analysis resulted in a 22-item model with two factors termed: (a) Ambiguity/Future Uncertainty (α = .93), and (b) Unpredictability (α = .89). The confirmatory factor analysis and a correlated uniquenesses model, which evaluated method effects, supported the two-factor model. DISCUSSION: These findings highlight the unique nature of illness uncertainty among adolescents and young adults and show the clinical and research utility of the MUIS-C for this population. Future investigations should examine how the two factors relate to distress among adolescents and young adults.

RESUMO

Recent research suggests atypical error-monitoring is important to understanding pathological anxiety. Because uncertainty is a transdiagnostic factor associated with anxiety and related disorders, recent research has begun to examine the influence of uncertainty in error-monitoring. Moreover, task irrelevant threat has been shown to influence cognitive performance in individuals with maladaptive anxiety. The current study aims to merge these literatures by examining the influence of task-irrelevant uncertain evaluative threat on error-monitoring using an event-related brain potential, the error-related negativity (ERN). Considering extensive literature indicating a relationship between worry and the ERN, worry was included as a continuous predictor in the analyses. Participants were randomly assigned to either a condition of negative or uncertain evaluative threat to determine their influence on error-monitoring in a Flankers task. Results for the ERN suggest that the ERN was significantly reduced only for the uncertain evaluative threat condition. The current study suggests that uncertain evaluative threat distractors result in a subsequent reduction in error-monitoring. This is consistent with literature suggesting that anxiety impairs inhibition of attentional processing of task irrelevant threatening information. This study adds to the burgeoning literature on the malleability of the ERN. Future research is needed to determine the mechanisms underlying this effect.

RESUMO

Past research suggests that social anxiety is associated with increased processing of cardiac activity. Cognitive theories propose that this is one aspect of self-focus, which is driven by concerns that features of the self, such as anxiety symptoms, will elicit evaluation from others. We investigated the relationship of social anxiety to the cortical processing of heartbeats as reflected in the heartbeat evoked potential (HEP) during false feedback of accelerated heart rate. Thirty-eight participants with high social anxiety (HSA; n = 19) and non-elevated social anxiety (NSA; n = 19) completed a cognitive task during which false feedback of accelerated heart rate was randomly provided on 50% of trials. HEP amplitude was larger in HSAs, but not NSAs, during false heartbeat acceleration cues compared to standard cues. HEP amplitude also was larger in HSAs compared to NSAs during acceleration cues. HEP amplitude during acceleration cues, but not standard cues correlated with social anxiety. Within the first second after the R-peak, social anxiety correlated with voltage at Fz from 223 to 305 ms. Social concerns about the consequences of anxiety symptoms accounted for an indirect relationship between social anxiety and the HEP. These data extend prior evidence of increased processing of cardiac activity in socially anxious individuals, providing support for cognitive theories.

RESUMO

Converging findings from recent research suggest a functional relationship between attention-deficit/hyperactivity disorder (ADHD)-related hyperactivity and demands on working memory (WM) in both children and adults. Excessive motor activity such as restlessness and fidgeting are not pathognomonic symptoms of ADHD, however, and are often associated with other diagnoses such as generalized anxiety disorder (GAD). Further, previous research indicates that anticipatory processing associated with anxiety can directly interfere with storage and rehearsal processes of WM. The topographical similarity of excessive motor activity seen in both ADHD and anxiety disorders, as well as similar WM deficits, may indicate a common relationship between WM deficits and increased motor activity. The relationship between objectively measured motor activity (actigraphy) and PH and visuospatial WM demands in adults with ADHD (n = 21), adults with GAD (n = 21), and healthy control adults (n = 20) was examined. Although all groups exhibited significant increases in activity from control to WM conditions, the ADHD group exhibited a disproportionate increase in activity, while activity exhibited by the GAD and healthy control groups was not different. Findings indicate that ADHD-related hyperactivity is uniquely related to WM demands, and appear to suggest that adults with GAD are no more active relative to healthy control adults during a cognitively demanding laboratory task.

RESUMO

OBJECTIVE: Research has demonstrated that a lack of social support is related to suicide risk. This study examines perceived burdensomeness and thwarted belongingness, of the Interpersonal Theory of Suicide, as mechanisms of the social support-suicide relationship in college students. METHOD: The study consisted of 207 students from a Midwestern university. Data were collected from 2007 to 2008. Two multiple mediation analyses were conducted to examine whether perceived burdensomeness and thwarted belongingness mediated the relationship between indices of social support and suicide ideation. RESULTS: Perceived burdensomeness mediated the relationships between perceived social support and suicide ideation (95% confidence interval [CI] -.02 to -.00, effect size = -.01) and social connectedness and suicide ideation (95% CI -.03 to -.00, effect size = -.03). Thwarted belongingness did not mediate either relationship. CONCLUSIONS: Results suggest that a lack of social support could lead to perceptions of being a burden on others, which could lead to suicide ideation.

RESUMO

Human life history (LH) strategies are theoretically regulated by developmental exposure to environmental cues that ancestrally predicted LH-relevant world states (e.g., risk of morbidity-mortality). Recent modeling work has raised the question of whether the association of childhood family factors with adult LH variation arises via (i) direct sampling of external environmental cues during development and/or (ii) calibration of LH strategies to internal somatic condition (i.e., health), which itself reflects exposure to variably favorable environments. The present research tested between these possibilities through three online surveys involving a total of over 26,000 participants. Participants completed questionnaires assessing components of self-reported environmental harshness (i.e., socioeconomic status, family neglect, and neighborhood crime), health status, and various LH-related psychological and behavioral phenotypes (e.g., mating strategies, paranoia, and anxiety), modeled as a unidimensional latent variable. Structural equation models suggested that exposure to harsh ecologies had direct effects on latent LH strategy as well as indirect effects on latent LH strategy mediated via health status. These findings suggest that human LH strategies may be calibrated to both external and internal cues and that such calibrational effects manifest in a wide range of psychological and behavioral phenotypes.

RESUMO

The current study documents the relationship between suicide ideation, grit and gratitude, and rumination subtypes of brooding and reflection. The relationship between rumination and suicide ideation has been well documented and previous research has demonstrated that grit and gratitude are protective factors against suicide. We hypothesized that both subtypes of rumination would have an indirect effect on suicide ideation through levels of grit and gratitude. Results of a conditional indirect effects path analysis indicated that brooding was indirectly related to suicide ideation through gratitude. Brooding interacted with grit such that it only predicted suicide ideation at low levels of grit. Reflection interacted with gratitude to predict levels of grit. Results suggest that brooding may impact suicide risk and resilience through its effect on gratitude, indicating important cognitive-behavioral targets for suicide prevention strategies. These results extend the literature about the relationship between well known risk factors for suicide and protective factors.

RESUMO

Research suggests that worry precludes emotional processing as well as biases attentional processes. Although there is burgeoning evidence for the relationship between executive functioning and worry, more research in this area is needed. A recent theory suggests one mechanism for the negative effects of worry on neural indicators of attention may be working memory load, however few studies have examined this directly. The goal of the current study was to document the influence of both visual and verbal working memory load and worry on attention allocation during processing of emotional images in a cued image paradigm. It was hypothesized that working memory load will decrease attention allocation during processing of emotional images. This was tested among 38 participants using a modified S1-S2 paradigm. Results indicated that both the visual and verbal working memory tasks resulted in a reduction of attention allocation to the processing of images across stimulus types compared to the baseline task, although only for individuals low in worry. These data extend the literature by documenting decreased neural responding (i.e., LPP amplitude) to imagery both the visual and verbal working memory load, particularly among individuals low in worry.

RESUMO

BACKGROUND AND OBJECTIVES: Worry and anticipatory processing are forms of repetitive negative thinking (RNT) that are associated with maladaptive characteristics and negative consequences. One key maladaptive characteristic of worry is its abstract nature (Goldwin & Behar, 2012; Stöber & Borkovec, 2002). Several investigations have relied on inductions of worry that are social-evaluative in nature, which precludes distinctions between worry and RNT about social-evaluative situations. The present study examined similarities and distinctions between worry and anticipatory processing on potentially important maladaptive characteristics. METHODS: Participants (N = 279) engaged in idiographic periods of uninstructed mentation, worry, and anticipatory processing and provided thought samples during each minute of each induction. Thought samples were assessed for concreteness, degree of verbal-linguistic activity, and degree of imagery-based activity. RESULTS: Both worry and anticipatory processing were characterized by reduced concreteness, increased abstraction of thought over time, and a predominance of verbal-linguistic activity. However, worry was more abstract, more verbal-linguistic, and less imagery-based relative to anticipatory processing. Finally, worry demonstrated reductions in verbal-linguistic activity over time, whereas anticipatory processing demonstrated reductions in imagery-based activity over time. LIMITATIONS: Worry was limited to non-social topics to distinguish worry from anticipatory processing, and may not represent worry that is social in nature. Generalizability may also be limited by use of an undergraduate sample. CONCLUSIONS: Results from the present study provide support for Stöber's theory regarding the reduced concreteness of worry, and suggest that although worry and anticipatory processing share some features, they also contain characteristics unique to each process.
